I'm curious to know if there is some kind of spreadsheet of XP earnings of different vehicles, or if they even have a coefficient.

I've thought since the Churchill III makes such abnormally high XP compared to other tanks even when having minimal contribution on the battlefield that there must be other vehicles that make higher than normal XP.

I'm asking this in particular for the ongoing event since we're being encouraged to buy nation specific camouflages for a 50% bonus and ideally I'd like to get this event done (or cut down) with as minimal battles as possible.

Update;

So it seems there is nothing we don't all already know about regarding XP earnings too discover. From what I've learned there is no XP coefficient.

The Churchill III is only special due to it having it's own XP multiplier.

XP is dependent on performance not the tank. If you played two identical games in two different tanks (of the same tier) you would get the same XP.

Are you sure that's true?. For instance, from my stats in T8:

M6A2E1 EXP - Winrate: 62.9% Average Damage: 1783, Average XP: 948

Lowe - Winrate 59.5% Average Damage: 1686 Average XP: 972

I know that doesn't account for all the other forms of XP, but the Lowe is neither mobile nor a spotting tank. Hard to believe I'm earning an average of 30xp more for doing 100 less damage and losing 3% more often.

The Churchill III is the only tank that I know definitely earns more XP for an equivalent game, probably about 1.4x normal. If you look at the tier 5 ace bar, the Church stands way out of the crowd with a median 1442 base XP required compared to 1127 as the next highest. For every other tier, the difference between highest and next-highest is much smaller.

So there are tanks that have technically higher XP earnings however the difference is so marginal from other tanks it's almost useless.

It seems a spreadsheet for XP earnings doesn't exist then unfortunately.

It might, but honestly I do not think it matters much for what you are talking about. Other than the Church 3, most tanks are similar enough at tier that your own preferences and performance bury any inherent difference by a factor of several. What you do well in and win in at higher tiers will trump any nominal difference between tanks. My strategy if grinding XP is to also grind credits so tier 8 premiums are the best fit.
